The patch affects only test suite and has the following changes:

1. On starting Instance Manager -- added code for waiting for guarded
mysqld instances to create PID files;
2. Polishing;
3. Move IM-related operations out of mtr_process.pl into new dedicated
for IM file -- mtr_im.pl

21913: DATE_FORMAT() Crashes mysql server if I use it through mysql-connector-j driver.

Variable character_set_results can legally be NULL (for "no conversion.")
This could result in a NULL deref that crashed the server.  Fixed.

(Although ran some additional precursory tests to see whether I could break
anything else, but no breakage so far.)

  Provide a more extensible, easier-to-change way of reordering
  test cases.

start instance; kill mysqlmanager; show ...

The problem was that Instance Manager didn't close client
sockets (sockets for client connections) on execing mysqld
instance. So, mysqld-instance inherits these descriptors.

The fix is to set close-on-exec flag for each client socket.

The problem was due to a prior fix for BUG 9676, which limited
the rows stored in a temporary table to the LIMIT clause. This
optimization is not applicable to non-group queries with aggregate
functions. The fix disables the optimization in this case.
